23.01.2023 Confirmed purchase Translated review
I tried to save a few zlotys by buying this (cheaper for about PLN 44) instead of the SparkFun model for about PLN 54, but I was disappointed in the library prepared by the manufacturer. Everything seems to work, but it won't let you have a lit colon all the time, because displaying new numbers or letters removes the colon and turning it back on takes 100ms, displaying anything on the display at all - even a colon, takes this library 100ms. I've tried to run on other libraries but haven't succeeded yet. Also, by default, ONLY capital letters and numbers can be displayed. no symbols, such as hyphens, asterisks or parentheses. When I later looked at the library that SparkFun provides for its display, I really regretted not spending ~ PLN 10 more. In addition, only 2 such displays can be operated and the board does not allow them to be placed close to each other. Nevertheless, the numbers and letters are displayed and look nice (when you correct the font manually, because, for example, S or Y are bright). Changing the brightness works OK, and it just works fast. The hit is that when there is a longer string to scroll, this action freezes the entire program/driver until the entire string is scrolled :D Tragedy with such scrolling!!!
